FEEDING-OFF MECHANISM.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed December 18, 1906. Serial No. 348,491.

ments of parts which will be hereinafter fully described and thenspecifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure1 is a sectional view showing in elevation parts of the invention. Fig.2 is a side elevation, parts being shown in section, and Fig. 3 is adetail view in elevation of the rollers and means for feeding the papersforward.

Reference now being had to the details of the drawings by letter, mdesignates the bottom of the box having a front wall m The bottom of thebox m is cut away at a point where the articles are to be fedtherethrough. Said rollers are mounted upon the shaft 61 with a spaceintervening between the same, as shown in Figs. 2 and 3 of the drawings.

62 designates a deflector which is hinged at n to the bottom of the feedbox m and an edge of a projection of said deflector has a cam surface62.

Mounted upon the body of the deflector 62 is a needle bar 63 which moveslongitudibox 64. The free swinging edge of said deflector has, it willbe noted, a diagonally disposed aperture p through which a portion ofthe bar 63 extends.

65 designates a needle held in a split end of said bar, and 66designates a clamp designed to frictionally hold the needle 65 withinthe aperture of the bar 63. Said clamp 66 has attached thereto a spring67, which latter is also fastened to a screw 9, and 68 designates aclamp upon the deflector, the purpose of which is to limitthe returnmovement of the bar.

Pivotally mounted upon the pin 1" upon a wing of the deflector is athrust pawl 69 designed to engage the head of a needle bar and to imparta longitudinal movement thereto, as said pawl is tilted. Fixed to theend of the feed roll is a stud 70 which is designed at each rotarymovement of the roll upon which it is mounted to engage the pawl 69 andtilt the same and also to contact with the cam surface 62 of thedeflector.

Mounted upon a shaft 71 is a feeding off roll 71 having a lipped recess72 in the circumference thereof, into which the article fed from the boxor receptacle enters as the rollers travel in the direction indicated bythe arrows.

In operation, the articles'to be fed out are placed-in the feed boxlying flat u on the bottom with their inner edges over apping the feedroll 60 and laid against the front end of the box m and directly incontact with the upper surface of the deflector 62. As the roll 60rotates in the direction shown by the arrows, the stud 70 first engagesthe thrust pawl 69, driving the needle bar 63 with its needle pointforward. The needle point perforates and engages the underlying articlesin the box or receptacle to be flexed into engagement with the feedrolls. As the stud is still carried further forward by the rotation ofthe roll upon which it is mounted, it will engage the cam surface 62 ofthe deflector 62, causing the deflector to tilt upon its pivot or hingen. This movement depresses the point of the deflector carrying thearticle into which the needle point was thrust down with it, therebyflexing the article into. contact or engagement with the lipped recess72 of the feeding olf roll 71, by which it is carried into the bite ofthe rolls 60 and 71. fed off out of the bottom of the feed box and fromwhich they may be carried to conveyer rolls or to any other location. Asthe article being fed off is carried down by the roll 71, the deflector62 is depressed to a position within the periphery of the roll 60, whereit remains until the article has passed, after which it is returned toits former position by the spring 72*. It will thus be observed that,when the stud 70 has passed the fulcrum of the thrust awl 69, the needlebar and the thrust pawl will be returned to their normal positions bythe spring 67.

My improved feeding off mechanism is de signed to be workedintermittently by any suitable mechanism and driven by means of Theserolls draw the article being a motor or other suitable power and theshafts 61 and 71 are adapted to be geared together in order that thestud 70 may maintain a consistent relative position to the gripping ed eof the feeding off roll 71.

What I c aim to be new is 1. A feeding off mechanism for articles,comprising a receptacle having an opening in the bottom thereof, ahinged deflector mounted in the bottom' of the receptacle, a movableneedle point carried by the deflector, a roller, means carried therebyfor tilting said deflector and operating the needle point, and a feedingoff roll having a lipped recess upon its circumference cooperating withthe deflector to receive an article to be fed between said rollers, asset forth.

2. A feeding off mechanism for articles,

comprising a receptacle having an opening in the bottom thereof, ahinged deflector mounted in the bottom of the receptacle,

means for operating said deflector a movable needle point carried by thedeflector, a roller, a stud mounted upon said roller, a thrust pawlpivotally mounted upon a wing of said deflector and in the path of saidstud, said.

. needle point being actuated by said pawl,

and a feeding off roll having a lipped recess in the circumferencethereof and ositioned adjacent to said stud carrying ro ler, as setforth.

} 3. A feeding off mechanism for articles, comprising a receptaclehaving an opening in the bottom thereof, a hinged deflector mounted inthe bottom of the receptacle, means for operating said deflector, aneedle carrying bar mounted upon said deflector, a needle carried bysaid bar, a spring fastened at one end to said bar and its other end tothe deflector, a thrust pawl pivotally mounted upon the latter, aroller, a stud mounted thereon and positioned in the path of said pawl,and a feeding off roll having a lipped recess in the circumference andpositioned adjacent to the stud carrying roll, as set forth.

4. A feeding ofl' mechanism for articles,

, comprising a receptacle having an opening in the bottom thereof, ahinged deflector mounted in the bottom of the receptacle, a needlecarrying bar mounted upon said deflector, a needle carried by said bar,a spring fastened at one end to said bar and its other end to thedeflector, a thrust pawl pivotally mounted upon the latter, a roller, astud mounted thereonand positioned in the path of said pawl, a wing ofsaid deflector having a cam edge also in the path of said stud, and afeeding ofl' roll having a lipped recess in its circumference andpositioned adjacent to the stud carrying roll, as set forth.

5. A feeding olf apparatus comprising a receptacle having an opening inthe bottom thereof, a deflector hinged to the bottom of said receptacle,means for operating said deflector a bearing box mounted upon a wing ofsaid deflector, a rod passing through said bearing box, one end of saidrod being split, a needle point mounted in said s lit end and extendingthrough a dia ona y disposed opening in the deflector, a c amping memberfixed to the split portion of the rod, a spring connecting said clampingmember and win of the deflector, a pivotal thrust paw i mounted upon thewing of the deflector, a roller, a stud mounted thereon and positionedin the path of said pawl, and a feeding ol'l' roll with a lipped recessin the circumference thereof mounted adjacent to said stud carryingpawl, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
